It is among the objects of my invention to provide an automatic cleaningunit that can clean lint and all foreign matters from a quill windermachine.

Another object of my invention is to provide an automatic air cleaningunit that can be put in and out of operation with the winding cycle ofthe quill winder machine.

Yet another object of my invention is to provide a cleaning unit thatcan be attached to the present quill winder as shown in W.V. Goodhue etal. U.S. Pat. No. 2,785,704 which is attached to the weaving loom asshown in U.S. Pat. No. 2,638,936.

Other objects and advantages of this invention will appear from thedescription herein below and the accompanying drawings wherein:

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cut away front view of thequill winder machine that is shown in FIG. 1 of W.V. Goodhue et al. U.S.Pat. No. 2,785,704 to which my invention of the cleaning unit isattached.

FIG. 2 is a rear view of the quill winder and an assembled view of myinvention of the cleaning unit that is connected to the quill winder andthe casted frame of the weaving loom.

FIG. 3 is an expanded over all view of the air tube positioning combbracket with an air tube connected to it by the means of a locking guideclamp.

FIG. 4 is an expanded side view of the comb bracket with an air tubelocked into position with the locking guide clamp.

FIG. 5 is a cut away portion along the line 5-5 of FIG. 2 that is anelevated view of the protruding retriever cycle lever and the microswitch.

FIG. 6 is a diagram of the electrical connections used in controling thecleaning unit.

DESCRIPTION OF THE PREFERRED EMBODIMENT The present invention is limitedto an attachment for known quill winders, especially those of the typedisclosed by the cited U.S. Pat. No. 2,785,704, and is not directed tothe winder structure per se. For classification, the disclosedembodiment may be considered as attached to the winder structure of saidpatent so that reference thereto may be had for structural andoperational details related to bobbin winding. As incorporated with thepresent invention, when the quill winder is actuated to accept an emptyquill for winding, the cleaning unit begins its cleaning operation whichcontinues until the winding of the bobbin is complete.

Referring now to the drawings in detail. As shown in FIGS. 1 and 2,bracket 30 attached to the quill winder frame adjacent to the windingarea mounts a plurality of air tubes 13 by means of locking clamps 31.The tubes 13 are positioned so that their nozzle end portions willdirect air, delivered under pressure, through tubes 13 over the windingarea and over a quill being wound therein.

The guide clamp is moved up or down inside the comb slots in order todirect the air in any position desired and is then locked into place bythe screw 33. To change the position of the air tubes 13 to the left orright the tubes are positioned in a different comb slot as desired. Thelocking clamp, FIG. 4, holds each air tube 13 in place by tighting thescrew 33 which will press the wings of said clamps against the back andfront walls of the comb bracket 30. The comb bracket is held in place onthe casted frame 9a FIG. 2 of the weaving loom by the means of the holes32 FIG. 3.

In FIG. 2 the compressed air supplied by any known means enters the mainpipe 24 that is connected the filter bowl 19 by the means of a nipple 20coupling 21 and a compression fitting 22,23. The filter bowl 19 is usedin extracting all water from the compressed air coming into the unit.

The solenoid valve 16 that stops and starts the flow of air into the airblock 10 is connected to said filter bowl by the means of a coupling 17and nipple 18. The air block 10 is connected to the solenoid valve 16 bya coupling 14 and nipple 1S. Said air block is mounted on the frame 9bof the weaving loom. The loom that is shown as aforesaid in U.S. Pat.No. 2,638,936.

The air tubes 13 are connected at one end to said air block by the meansof compression fittings 11,12. At the other end the tubes are connectedto the comb bracket 30 in their desired positions by the means of thelocking clamp 31. The said comb bracket is mounted on the frame 9a ofthe loom. Let it be known that the air tubes 13 are made of a flexiblematerial for the shaping and placing in the desired slots and positionsof said comb bracket.

Solenoid value 16 is controlled by on electrical circuit generallyillustrated in FIG. 6. The circuit, including leads 34 and 35, isconnected with a power source and has a manually operated control suchas toggle switch 25. Also included is a micro switch means 26,27,28which may be automatically operated to interrupt or complete the circuitwith solemoid 16. The micro switch is controlled between open and closedpositions by lever 29 which operates in synchronism with the operationof the quill winder. The retriever lever 29, FIG. 5, moves to the leftwhen the quill winder 9 starts its cycle to wind a bobbin 36, FIG. 1.The lever 29 then pushes the hinged lever 27 to operate the circuit 28which then opens the solenoid valve 16 and allows the air to go into theair block 10 where it is distributed into the tubes 13. When the bobbinis wound and the cycle is finished the lever 29 moves to the right andbreaks the circuit in the micro switch 26 whereby the solenoid valvecloses and stops the air going through to clean the quill winder machineuntil the next cycle starts.

The air coming out of the tubes 13 FIG. 1 is generally indicating thecleaning of all lint and foreign matters from the quill winders movingparts such as the yarn guide 38 bobbin 36 traverse bar 37 bobbin grips39 and many other moving parts not shown.

I claim:
